            This information describes the <code class="classname">DbMemoryException</code> class and how 
            it is used by the various Berkeley DB classes.
    </p>
      <p>
            A <code class="classname">DbMemoryException</code> is thrown when there is insufficient memory to
            complete an operation, and there is the possibility of recovering. An example is during a
            <a class="xref" href="dbget.html" title="Db::get()">Db::get()</a> or 
            <a class="xref" href="dbcget.html" title="Dbc::get()">Dbc::get()</a> operation with the 
            <a class="link" href="dbt.html" title="Chapter 4.  The Dbt Handle">Dbt</a> flags set to 
            <a class="link" href="dbt.html#dbt_DB_DBT_USERMEM">DB_DBT_USERMEM</a>.
    </p>
      <p>
            The <a class="link" href="dbexception.html" title="Chapter 6. The DbException Class">DbException</a> errno value is set to
            <code class="literal">DB_BUFFER_SMALL</code> or <code class="literal">ENOMEM</code>.
    </p>
      <p>
            The <code class="methodname">get_dbt()</code> method returns the 
            <a class="link" href="dbt.html" title="Chapter 4.  The Dbt Handle">Dbt</a> with insufficient memory to complete the
            operation, causing the <code class="classname">DbMemoryException</code> to be thrown.
            The <a class="link" href="dbt.html" title="Chapter 4.  The Dbt Handle">Dbt</a> pointer may or may not refer to valid
            memory, depending on whether the <a class="link" href="dbt.html" title="Chapter 4.  The Dbt Handle">Dbt</a>
            used in the call to the failed Berkeley DB method is still in scope and has not been
            deleted.
